Urban heat in rapidly growing megacities is spatially uneven, yet the relative influence of built form, socioeconomic activity and blue-green spatial configuration remains insufficiently resolved in cities of the Global South. This study examines neighbourhood-scale controls on land surface temperature (LST) in Delhi, India, using a single clear...

Excerpt from Preface: Climate action has long been the main focus of global sustainability efforts. From a biodiversity point of view, frameworks to manage greenhouse gases need to do more than track emissions. They should, at least, avoid harming biodiversity and at best be proactive tools for sustaining the complex ecosystems that help us...

本業務は、アジア太平洋地域の国々の取組強化に資するとともに、同地域の動向や先駆的な取組を国際社会へ発信し、国連における2030年以降の持続可能な開発に関する国際枠組の議論へのインプットを目指すため、アジア太平洋地域特有の観点からシナジー推進の優良事例や展開方策を「アジア太平洋シナジーレポート」としてとりまとめることを目的としたものである。昨年度（令和6年度）業務において策定された企画書に基づき、ESCAP、UNEP、ADB等の関係機関と調整しつつ、生物多様性や都市等の個別テーマ（チャプター）の検討、地域特有の課題抽出、及びシナジーアプローチ実施に向けた提言の策定に向け、事務局として各種とりまとめ作業を進めた。

Accelerating urban population concentration across the world has both positive and negative social-ecological consequences. Countries facing serious negative consequences like Japan need to explore enhanced deurbanization pathways, e.g., highlighting high quality of life in rural areas, to achieve a more desirable urban-rural population balance...

Urban trees play a crucial role in regulating hydrological processes within urban ecosystems by intercepting rainfall to effectively reduce surface runoff and mitigate urban flooding. Current research lacks a systematic quantification of rainfall interception capacity and its community-level impacts at the urban scale. This study adopts a city...
